As part of a Nordic comparative study on sectorized psychiatry, sociodemographic characteristics (gender, age and marital status) were studied in relation to treated incidence in eight diagnostic subgroups.

Women with a neurosis diagnosis had a significantly higher relative probability of contact with all services.

Men with a dependence diagnosis had a significantly higher relative probability of contact with four of the seven services.

Older people had a significantly higher relative risk for affective psychosis in six of the seven centres, and younger individuals had a significantly higher relative risk for personality disorders in six of the seven centres.

Unmarried people showed a higher relative risk for functional psychosis and personality disorders in five of the seven services.
